Objective To determine whether the use of serum insubetween these groups. The PSA level and age of the patients diCered significantly between the groups (both lin-like growth factor 1 (IGF-1) levels is more eBcient than serum prostate specific antigen (PSA) levels in P<0.001). There was no correlation between IGF-1 and PSA levels, and even when the age diCerence in predicting prostate cancer in patients undergoing prostatic biopsy.the groups was considered, there was still no significant relationship between IGF-1 levels and the inciPatients and methods The study included 94 consecutive patients who required transrectal ultrasonography dence of prostate cancer. In patients with a PSA level of 4-20 mg/L there was no statistically significant (TRUS)-guided biopsies of their prostate and who had blood samples taken before their biopsies. These diCerence in IGF-1 levels between the groups. Conclusion Serum IGF-1 as a tumour marker does not samples were then analysed for IGF-1 and PSA concentrations. Six prostatic biopsies were taken from each help to predict patients with prostate cancer. PSA level and even age were better predictors of the presence of patient; they were assessed and a diagnosis made of prostate cancer or no malignancy.prostate cancer than were serum IGF-1 levels.
The empirical physiological formulae of the new continuous cardiac dynamic monitoring HeartSmart ® technology, which involves the use of a new inverse square rule of the heart, were investigated with pulmonary artery catheter (PAC) thermodilution in the estimation of CI in diverse patients. Clinical trial data collected from 268 adult surgery or intensive care patients requiring PAC placement were obtained from 7 NHS Trust hospitals, providing 2720 paired sets of CI estimations for comparison between HeartSmart ® and PAC thermodilution. For 95% of pairs of measurements, HeartSmart ® values were between 57% and 164% of PAC measurements; additionally, the larger limit of agreement between HeartSmart ® and PAC thermodilution (1.26 L min-1 •m-2) suggests that HeartSmart ® agrees with PAC thermodilution as closely as PAC thermodilution agrees with itself. HeartSmart ® can also estimate CI in the extreme circumstances of shock/sepsis, as indicated by PAC thermodilution CI values that were hypo-or hyperdynamic based on systemic inflammatory response syndrome criteria. In CI measurements for hypo-or hyperdynamic values that were matched between HeartSmart ® and PAC thermodilution, the difference in total volumes and average CI measurements between the two methods was less than 5%. For unmatched hypo-or hyperdynamic values, the difference between total volumes and average CI measurements was less than 33%-an acceptable percentage of difference or error even for normal values of CI. HeartSmart ® tracked PAC thermodilution CI hypodynamic values 98.2% of the time and hyperdynamic values 97.6% of the time. These findings show that CI estimations provided by the HeartSmart ® empirical physiological formulae are comparable to those obtained using PAC thermodilution. HeartSmart ® removes many of the technical barriers that prevent the routine adoption and practice of early goal-directed therapy, and represents a simple, reliable method of estimating CI and other hemodynamic variables at the bedside or in departments other than the Intensive Care Unit.
In vitro fungicidal properties of cecropin B and dermaseptin were explored using non‐germinating and germinating conidia from Aspergillus flavus, A. fumigatus, A. niger, Fusarium moniliforme and F. oxysporum. Cecropin B produced LD50 values for germinating
A. flavus, A. fumigatus and A. niger conidia of 3·0, 0·5 and 2·0 μm, respectively, while dermaseptin gave LD50 values of 4·0, 0·05 and 2·0 μm, respectively. Cecropin B produced an LD50 value of 0·2 μm for non‐germinating F. moniliforme and F. oxysporum conidia, while dermaseptin did not reduce either as much as 50% at any level tested. LD50 levels for CB were 0·2 and 0·1 μm, respectively, for germinating F. moniliforme and F. oxysporum conidia. Dermaseptin was less effective, giving LD50 values for germinating F. moniliforme and F. oxysporum conidia of 0·3 and 0·8 μm, respectively. Neither peptide reduced conidial viabilities of non‐germinating Aspergillus spp. Physicochemical studies indicated cecropin B and dermaseptin bound to ergosterol and cholesterol, conidial wall constituents, but not to chitin or β‐1,3‐glucan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
